Plasmodium: Plasmodium is a common spore-forming sporozoan parasite on human which causes malaria. One such approach is target repurposing, where pathogen targets are matched with homologous human targets that have been pursued for drug discovery for other indications. *Department of Pediatrics, Division of Pediatric Infectious Diseases, University of South Alabama College of Medicine, Mobile, AL. 2014 Sep 1;24(17):4084-9. doi: 10.1016/j.bmcl.2014.07.063. Drug repurposing and human parasitic protozoan diseases. enquiries. Diseases Caused By Protozoa: Literally meaning “first animals“, protozoans are considered to be one of the very first organisms to thrive in the planet. The researchers began by performing a broad analytical study of existing drugs, looking for any with the potential for repurposing as a Cryptosporidium treatment. This review focuses on drug repurposing for the human parasitic protozoan diseases malaria, trypanosomiasis, leishmaniasis, toxoplasmosis, and cryptosporidiosis. Parasitic diseases have an enormous health, social and economic impact and are a particular problem in tropical regions of the world.

Intestinal protozoal diseases clinical presentation: history, physical. Unfortunately, where drugs are available, their usefulness is being increasingly threatened by parasite drug resistance. Although this is true for many parasitic infections, a number of infections continue to occur in developed countries and have a substantial public health impact. But in the absence of an effective vaccine, drugs are used against parasitic diseases. International Journal for Parasitology: Drugs and Drug Resistance 4, 95 ... Yeast as a potential vehicle for neglected tropical disease drug discovery. The global burden of these diseases is exacerbated by the lack of licensed vaccines, making safe and effective drugs vital to their prevention and treatment. In this review we discuss one of these approaches, drug repurposing or repositioning, with a focus on major human parasitic protozoan diseases such as malaria, trypanosomiasis, toxoplasmosis, cryptosporidiosis and leishmaniasis Publisher: Published by Elsevier Ltd. Year: 2014. Other protozoan disease include: African trypanosomiasis ("sleeping sickness") : Caused by Trypanosoma brucei gambiense (98% of cases) and Trypanosoma brucei rhodesiense (2%). A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. Infections caused by protozoan parasites burden the world with huge costs in terms of human and animal health. 4 National Research Center for Protozoan Diseases, Obihiro University of Agriculture and Veterinary Medicine, Inada-cho, Obihiro, Hokkaido 080-8555, Japan. Current treatments using anti-parasitic drugs are toxic and prolonged with poor patient compliance. For these reasons, the discovery of new etiological treatments is necessary. Of all parasitic diseases, malaria causes the most deaths globally. Drug repurposing and human parasitic protozoan diseases. By continuing you agree to the use of cookies. Human parasite diversity is very large, ranging from protozoa to worms. The trypanosomes, for example, cause a number of important diseases in humans. https://doi.org/10.1016/j.ijpddr.2014.02.002. Protozoan Disease # 7. Diseases caused by protozoa and helminths, such as malaria and schistosomiasis, are the cause of most parasite related morbidity and mortality, with an estimated 1.1 million combined deaths annually. Parasitic infections are traditionally considered diseases of poor countries. Drug repositioning has played a key part in improving the lives of those suffering from these conditions, as evidenced by successful precedents and recent studies on preeminent parasitic disorders. Parasitic protozoan infections represent a major health burden in the developing world, causing high rates of morbidity and mortality. Because drugs in use against HAT are toxic and require intravenous dosing, new drugs are needed. Protozoan Disease # 2. Drug repurposing and human parasitic protozoan diseases @article{Andrews2014DrugRA, title={Drug repurposing and human parasitic protozoan diseases}, author={K. Andrews and Gillian M. Fisher and T. Skinner-Adams}, journal={International Journal for Parasitology: Drugs and Drug Resistance}, year={2014}, volume={4}, pages={95 - 111} } Initiating lead discovery campaigns by using chemical scaffolds from drugs approved for other indications can speed up drug discovery for neglected diseases. Areas covered: Herein, the authors investigate two strategies, namely whole organism screening and target-based drug design. Histone deacetylase (HDAC) inhibitors are being investigated as drugs for a range of diseases, including cancers and infectious diseases such as HIV/AIDS, and several parasitic diseases. ChemMedChem. You may not alter, transform, or build upon this work. In addition, emergence of drug-resistant parasites is increasing worldwide.

Unfortunately, where drugs are available, their usefulness is being increasingly threatened by parasite drug resistance. Most PPDs are widely regarded as poverty- Malaria kills more than 400,000 people each year, most of them young children in sub-Saharan Africa. Drug repurposing can result in significant time and cost savings. - "Drug repurposing and human parasitic protozoan diseases" Because drugs in use against HAT are toxic and require intravenous dosing, new drugs are needed. Diseases caused by protozoa and helminths, such as malaria and schistosomiasis, are the cause of most parasite related morbidity and mortality, with an estimated 1.1 million combined deaths annually. The global burden of these diseases is exacerbated by the lack of licensed vaccines, making safe and effective drugs vital to their prevention and treatment. While drug repurposing is the process of finding new indications for existing drugs. In most cases, more effective and new drugs are urgently needed.
